The same year that Masekela’s song came out, the South African band Savuka, fronted by Johnny Clegg, released “Asimbonanga,” which roughly translates as “We have not seen him.” Mandela would dance to that one, too—and you can watch him do so below. He joins Clegg on stage, and then, after the song ends, Mandela insists they play it again, so people can dance more than they did the first time. “It is music and dancing,” he says, “that makes me at peace with the world.”
